The aluminum welding wire is employed as
filler metal for gas welding and arc welding. While for submerged arc electroslag
welding, this aluminum solder can function as filler metal as well as
conductive electrode. Due to the favorable welding strength, it is fit for work
pieces with larger gaps. Additionally, during welding, this kind of solder is
easy to form high compactness joint and fill the gap. It is especially suitable
for electrical industry.

1. Before welding, workers should
ensure the parent metal is clean and clear from any oil stain.

2. During welding, move back and
forth the welding gun to heat the soldering position uniformly. Heat the thick
metal first and then the thin one. When the metal temperature reaches 450 to
500°C, pour aluminum welding wire into the position. Later, make a slight heat
on the position and then move the gun, allowing it for self cooling.

The flame for
aluminum to aluminum soldering should be soft. The welding temperature shall be
580°C and aluminum parent metal temperature should be 630°C.
